1. Sandbox mechanism Introduction The sandbox mechanism (sandbox) in iOS is a security system.Each IOS application has a separate file system (storage space) and can only operate on the corresponding file system, which is called a sandbox. All non-code files are saved here, such as property files plist, text files, ima

The main criterion for judging the health of the PC chassis is whether the radiation capability is excellent, and the primary factor in judging the radiation is the material of the chassis. Typically, all parts and enclosures inside the quality chassis are not painted, because the paint contains resin ingredients, it will oxidize the plate and reduce the

, carefully inserted large fan, the central fan with a trademark circular adhesive carefully opened, you can see the center of the central Axis exposed, with Vaseline (very cheap, pharmacies have to sell) carefully coated, carefully sealed with a trademark of the round stickers can be. -Principle: Vaseline mostly used to smear hands, to prevent dry skin in winter, chapped, it has a feature: when the fan will produce heat when working, Vaseline will gradually melt into the fan bearing lubrication

The iOS sandbox mechanism sandbox is a separate storage area used by the system to save non-code files.　　So all non-code files are to be saved in this, examples like, icons, sounds, images, attribute lists, text files, etc. 1.1, each application has its own storage space 1.2, the application can not turn over their walls to access the contents of other storage space 1.3, the application request data must pa

With the improvement of computer multimedia technology, sound card, multimedia speaker technology, we have to enjoy high fidelity through the computer's sound is not difficult. As a basic index of high fidelity sound, signal-to-noise ratio (SNR) is also improved in multimedia audio system. But we in order to improve the sound card, speaker signal-to-noise ratio, but forgot to reduce the noise inside the computer chassis, so that our efforts in vain.

Let's see how to get the application sandbox directory. The directory that includes the sandbox for the real machine.1, get the program's home directory NSString *homedirectory = Nshomedirectory (); NSLog (@ "path:%@", homedirectory); Printing results: 2012-06-17 14:00:06.098 iossandbox[3536:f803]/users/rongfzh/library/application Support/iPhone SIMULATOR/5.

Computer radiation on human harm is obvious, and the basic way to prevent radiation is to choose a radiation-proof chassis, this article gives you how to buy radiation-proof chassis and some skills experience. 1, Chassis materials: selection of imported galvanized steel sheet material, thickness should be more than 1mm, the surface has an electrolytic layer prot

In our DIY long "levy Machine" on the road, there has been the disaster of static electricity, I was deeply affected by static electricity, hard to explore, to find the way to eliminate static electricity, the following article on how I eliminate static electricity "suffering" experience, I hope to give you a little help. Remember the computer just assembled back, the use is very normal, once accidentally touched the chassis rear panel (

Sandbox security model, class loading, class File validation, Sandbox class This article is mainly used for self-learning records. I will not list them one by one based on some blogs on the Internet.
